let x be the length of rectangular
\n" ); document.write( " width =x-15
\n" ); document.write( " perimeter = 86 meters
\n" ); document.write( " formula : perimeter = 2( length+width)
\n" ); document.write( " 86 = 2(x+(x-15))
\n" ); document.write( " 86 =2(2x-15)
\n" ); document.write( " 86 =4x-30
\n" ); document.write( " 86+30 = 4x
\n" ); document.write( " 116 = 4x
\n" ); document.write( " divide with 4 on both sides
\n" ); document.write( " $\"++116%2F4++=+4x%2F4\"$
\n" ); document.write( " $\"29+=x\"$
\n" ); document.write( " length (x) =29 m
\n" ); document.write( "width (x-15) = 29-15
\n" ); document.write( " = 14 m
\n" ); document.write( " Result : length =29 m , width = 14 m\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
